5. GROTIUSELLA THOREAUINI new species. 
Female: — ^Length, 1.30 mm. Hind tibial spurs short, unequal. 
Dark metallic green, the wings hyaline, the legs white, except the dusky caudal femora 
centrally, the caudal tibiae just below knees for half way to apex and middle tibiae just below 
knee at proximal fourth. Head pale whitish except occiput and center of vertex broadly. 
Antennal yellowish, the scape and pedicel whitish, the pedicel dusky (or metallic?) above. 
Mandibles with two outer acute longer teeth, then obliquely truncate and with four minute 
■comblike teeth. Body marked with golden yellow as follows: — A rather large spot on each 
side of meson of neck of pronotum; an oblique line down scutum on each side (distad along 
mesal margins of the axillm, the latter cephalad of the seutellum) like parapsidal furrows but 
constricted at about cephalic fourth; all margins of seutellum except at meson of base; 
lateral and caudal margins of axilla?, the caudal yellow joining the long oblique streak on 
scutum at its apex; mesopostscutellum ; a stripe on abdomen just out from base, bluntly 
incised at meson of cephalic margin and at each lateral running more narrowly to base; two 
cross-stripes distad of this both broadly interrupted along the meson; a broader, complete 
stripe distad of these and a little distad of middle; a similar stripe next but broadly inter- 
rupted at meson and a little shortened laterad; then a complete stripe of same length and 
.still some distance from apex. Propodeum glabrous at meson, with a median carina and no 
others; scaly laterad. Thorax densely scaly, the pubescence very sparse. Antennal club 
apparently 2-jointed bnt closer scrutiny shows that no articulation is j)rGsent; ring-joint 
extremely short; fuuicle 1 longest, subquadrate, larger than the globular pedicel, the following 
joints distinctly wider than long, each widening a little in succession. 
Coloured like species of Gyrolasella for which I mistook it. 
Respectfully dedicated to Henry David Thoreau. 
Described from one female taken by sweeping bushes, October 10, 1913 (G. F. Hill). 
Eahitat: Port Darwin, Northern Territory. 
Type: No. HyS705, Queensland Museum, Brisbane, the female on a tag; head and hind 
tibise on a slide. 
6. GROTIUSELLA PEARSONI new species. 
Female: — ^Length, 1.35 mm. 
Very similar to hyatU l)nt the cheeks are green and the stripe down the face along the 
eyes is first interrupted dorsad of middle and for the second time, a little ventrad of middle, 
some distance dorsad of ventral end of the eye; the legs are wholly lemon yellow, the apex of 
postscutelhun is metallic green rather broadly, the whole of base of sentellum is metallic green; 
the venter and sides of a>)domen are deep golden yellow; jnoreover, the broken cross-stripes of 
abdomen are rather S])ots (counted as stripes, there are but five-— the first and last complete 
■striijes, the fourth consisting of Uvo round marginal spots, the third a rather broad stripe 
interrupted at meson, the second two wider than long marginal S])ots) ; first stripe rather 
broad, incised at meson of cephalic margin. Propodeum glabrous except laterad of spiracle. 
Otherwise as in hyatti. 
From one female captured in the same place as hyatii, described below, on May 9, 1914. 
Eahitat: Chindera (Tweed River), New South Wales. 
Type: No. Ey^706, Queensland Museum, Brisbane, the specimen on a tag with type 
.of hyatti, head and caudal tibiae on a slide. 
Dedicated to Karl Pearson.
